I will have hard time to fall back to sleep if I was awoke

If someone awoke me at the middle of night, such as a sudden cell phone ringing, or my parents woke me up at the middel of night, I might have hard time to fall back to sleep again. I don't know why, and it was just me. Once, my cell phone ring at the middle of night, it was a call from my drunk cousin, after I hung it up, I start toss and turn, and I had a hard time to fall back to sleep. It will be much more difficult for me in the morning, since I didn't have good night sleep at night. Do you have the same problem?
